If converting a single-drive device, the conversion should only be done with a non-NVM Express (NVMe) solid-state drive (SSD) of at least 1 TB in capacity. 60 GB of free space will be allocated to the OS partition.

For multiple-drive devices, Datto recommends a non-NVM Express (NVMe) 120 GB SSD for the OS drive, and either non-NVM Express (NVMe) SSDs or 7200 RPM HDDs for the storage array

For multiple-drive devices, the OS drive must have at least 60 GB free space for the Datto OS. The total capacity of the drive should not exceed 1 TB.

All SATA hardware to be imaged must have the External Device option for its port set to Disabled in the device BIOS.

Unsupported Hardware

Pre-existing RAID configurations, both hardware and software, are unsupported. The SIRIS imager will create its own software RAID configuration during the conversion process. If the target hardware is equipped with hardware RAID, disable it. If possible, enable HBA mode (sometimes called Initiator-Target mode or Integrated RAID mode; see Oracle's documentation on the subject(external link) for more information.

Recommended Configurations for Imaged Datto Appliances

For best performance, Datto recommends that the target hardware meet or exceed the following configurations. Allocating fewer system resources than recommended can result in performance limitations during restore and disaster recovery. The imager can create RAID configurations up to RAID 10.
